#10. Cake sale
bake as many cakes as you can, or better still get your colleagues, friends, family to bake as many cakes as they can, and sell at a central location. You could even turn it into a Bake-off type competition if you like, selling the winners (and losers) cakes either to the highest bidder or suggest a donation. A cake sale can be an event all by itself or it could be a stall as part of a bigger event celebrating local creativity and taste.
